IMPROVEMENTJN BOOT AND SHOE LASTING MACHINES.

Specification forming part of Letters Patent No. 182,246, datedSeptember 12, 1876; application filed February 24, 1876.

To all whom it may concern:

of Newark, in the county of Essex, State of New Jersey, and GEORGE W.PIKE, of Milford, county of New Haven, State of Connecticut, haveinvented certain new and useful Improvements in Machines for LastingBoots and Shoes, of which the following is a specification:

This invention relates to mechanism for drawing the uppers of a boot orshoe over a last, so that it may be secured to the sole for beingafterward stitched or otherwise properly fastened thereto, by hand ormachinery; and the invention consists, substantially, of mechanismarranged and operating all substantially as hereinafter described.

In the accompanying plate of drawings, Figure 1 is a vertical section ofour invention; Fig. 2, a side elevation; Fig. 3, a plan view, and Fig.4, a view in detail.

A, in the drawings, represents a pair of spring-pinchers, havinggriping-jawsB and B Thesepinchers are secured by the extension a ofonejaw, B, in and to a holder, 0, by means of substantially a ball, b,and socket, 0, joint, whereby the pinchers A can have, in the presentinstance, a vertical swinging motion.

The holder 0 is arranged and adapted to be moved forward and backward ina slot, d, in the standard D, by and through the lever E. to which theholder 0 is connected, hinged at e in the standard, substantially asshown; F, a hammer, hung in slot f on a pivot, g, of holder, andarranged and adapted to bear upon the extension h of jaw B of pinchersA, to close the jaws B and B when desired, by the spring G bearingagainst the part of hammer F, the spring G being secured to holder M, asshown.

The hammer F is held in the position shown in Fig. 1 against the springG by the pawl or trigger H catching in the notchnof hammer F.

In the use of the hereinabove described mechanism, the pinchers arecarried forward, and with their jaws open and other parts as shown inFig. 1, in section and dotted lines, to the last, so that the upper isin and between the two jaws, when, by pulling the lever E backward,carrying with it the holder, trigger,

and pinchers, the triggerH by end 0 is acted (the upper) is brought tothe edge of the sole of the last, to be there held until properlysecured in the usual manner. 1

When the holder and pinchersare in the position last described, and asis shown in Fig. 2, a spring-catch, L, catches on the pin P of hammer F,as shown in Fig. 2. This spring-catch L serves, on the forward movementof the holder, hammer, pinchers, &c., necessary for a second operationsimilar to the above, to hold the hammer F, causing it to swing on itspivot g, and thereby release its hold upon the pinchers, until, when theforward movement is completed, the trigger H catches by the force of itsspring u in the notch n, and thus holds the hammer up; the

spring-catch L then striking the pin 9 on holder, is released from itshold on the hammer, as above described, when all parts are in positionand free for a second operation, while at the same time, by a relativemovement by hand or by machinery, the last, sole, and upper arepresented in another position ready for the seizure at a new point onthe upper by the pinchers, and again pulling it over the sole as before,and so on until the work is finished.

The vertical swinging movement of the pinchers, as above described, isrequisite to adapt them to the varying width of the sole of the boot orshoe in following the line of the shank, ball of the foot, &c. By theplate S the pinchers are prevented from accidental displacement fromtheir socket, and by taking off the plate S they can be easily removedwhen desired. g

In lieu of connecting the pinchers A to the holder 0, in the mannerdescribed, they can be connected in any of the obvious forms of hinge orpivotjoints, the swinging movement being necessary for the purposestated.

and backward movement of the pinchers, and

also in connection with suitable mechanism for each portion of the edgeof the upper to be successfully drawn by the pinchers over the last tothe sole located on the last; and when so applied, its special operationis to draw the edge of the upper over the last to the sole, and therehold it as it is fastened thereto at such point by the operation of themechanism last referred to above.

Fig. 4 represents a plan view of the under side of holder and its parts,except pinchers, as represented in Fig. 2.

The spring-catch L and pin I can be adjusted as desired for effectiveworking through the slots in their supports M and J.

Having thus described our invention, What we claim, and desire to secureby Letters Patent, is

1. Ina machine for lasting boots and shoes, the pinchers A, having thejaws B B and shanks a and h, the shank at having a ballhead, incombination with the socketed holder (3, substantially as and for theobject specified.

'2. In a machine for lasting boots and shoes, the pinchers A,constructed to have a swinging movement imparted to them, in combinationwith the sliding holder 0, substantially as and for the objectspecified.

3. In combination with the standard D, the holder 0, pinchers A, hammerF, spring Gr, trigger H, spring uand pin I, when all are arrangedrelatively to each other for operation substantially as described, forthe purpose specified.

4;. In combination with the standard D, holder 0, pinchers A, hammer F,spring Gr, trigger H, spring a, and pin I, the spring-catch L,substantially as and for the object specified.

5. The spring-catch L, in combination with the hammer F, substantiallyas and for the object specified.

The above specification of our invention signed by us this 8th day ofJanuary, A. D. 1876.
